Claims

[Scope of utility model registration request]

A device for opening and closing the opening of a hatch for transporting equipment, etc. into and out of a reactor containment vessel, which includes a lid member that covers the opening of the hatch, and an outer end located outside the opening for opening and closing the lid member. a hinge member that is rotatably supported and whose inner end supports the lid member rotatably around the axis of the opening; and a lock member that is arranged along the outer periphery of the lid member. a rod member arranged around the outer periphery of the opening and which engages the corresponding locking member when the lid member is rotated; a rotating means provided on the hinge member for rotating the lid member; What is claimed is: 1. A hatch opening/closing device characterized by comprising: a sealing means provided between the joining surface of the part and the lid member, and sealing means for sucking and sealing the space therebetween.
